Description

BACKGROUND

The present invention relates to a method for providing communication services of a mobile communication network to a plurality of telecommunication devices, wherein the mobile communication network is able to offer a plurality of available service capabilities to the plurality of telecommunication devices or to a subset of the plurality of telecommunication devices, the available service capabilities corresponding to groups of service capabilities such that the mobile communication network provides a varying degree of mobility functionality and/or a different quality of service levels and/or different levels of security measures and/or a varying degree of identity handling.
Furthermore, the present invention relates to a mobile communication network for providing communication services to a plurality of telecommunication devices, wherein the mobile communication network is able to offer a plurality of available service capabilities to the plurality of telecommunication devices or to a subset of the plurality of telecommunication devices, the available service capabilities corresponding to groups of service capabilities such that the mobile communication network provides a varying degree of mobility functionality and/or a different quality of service levels and/or different levels of security measures and/or a varying degree of identity handling.
Additionally, the present invention relates to a telecommunication device adapted to be used in connection with such a mobile communication network, and to a system comprising a mobile communication network and a plurality telecommunication devices.
Furthermore, the present invention relates to a program and to a computer program product for providing communication services of a mobile communication network to a plurality of telecommunication devices.
Within the framework of the fifth generation of mobile networks or mobile communication networks, a mobile communication network has to fulfil a broad range of requirements beyond what has been required for previous generations of mobile communication networks.
The range of requirements includes the support of efficient usage of bandwidth beginning from a data rate of a few kilobits per second up to a data rate of several Gigabits per second, from highly demanding latency requirements down to 1 ms to far less stringent delay requirements for some application like maschine-2-maschine communication where only several bytes per day need to be transferred in a not very time critical manner.
Mobility requirements range from stationary or almost stationary scenarios with millions of connected devices (Internet of Things) to highest speed mobile broadband connection in fast moving cars or trains.
Given this broad range of applicable requirements, it is a challenge to provide a mobile communication network that fulfills these very different requirements still in a very efficient manner.
US 2003/0083041 A1 discloses a method of initiating a wireless communication session with a communication network, wherein a cost estimate for the communication session is determined based on a quality of service level and a quantity of information to be communicated.

SUMMARY

An object of the present invention is to provide a technically simple, effective and especially cost effective solution for providing communication services of a mobile communication network to a plurality of telecommunication devices such that a differentiation of providing the communication services according to the respective requirements of the telecommunication devices is possible, especially with regard to service capabilities of the mobile communication network corresponding to groups of service capabilities such that the mobile communication network provides a varying degree of mobility functionality and/or a different quality of service levels and/or different levels of security measures and/or a varying degree of identity handling. A solution according to the present invention should provide a possibility to allow a mobile radio network (or mobile communication network), especially a fifth generation mobile radio network, to expose its network service capabilities to the outside world and further to allow on-demand provision of network services (or service capabilities) to telecommunication devices.
The object of the present invention is achieved by a method for providing communication services of a mobile communication network to a plurality of telecommunication devices, wherein the mobile communication network comprises an access network and a core network, the access network comprising a plurality of radio cells of the mobile communication network, wherein the mobile communication network is able to offer a plurality of available service capabilities to the plurality of telecommunication devices or to a subset of the plurality of telecommunication devices, the available service capabilities corresponding to groups of service capabilities, the groups of service capabilities including at least

-- the mobile communication network providing a varying degree of mobility functionality,
-- the mobile communication network providing different quality of service levels,
-- the mobile communication network providing different levels of security measures,
-- the mobile communication network providing a varying degree of identity handling, wherein the method comprises the step of establishing a connection or initiating an exchange of data between the mobile communication network and the plurality telecommunication devices, wherein prior to or upon
-- the establishment of the connection or
-- the initiation of the exchange of data

-- either indicates different available service capabilities within the groups of service capabilities, especially reflecting the situation - especially the network load - of the mobile communication network at the time of the further service capability information,
-- or indicates a different charging information related to different available service capabilities within the groups of service capabilities, especially reflecting the situation - especially the network load - of the mobile communication network at the time of the further service capability information.

It is thereby advantageously possible according to the present invention that a flexible method for providing communication services of a mobile communication network is provided such that the mobile communication network offers and is able to provide a plurality of available service capabilities in groups of service capabilities, and thereby offering or being able to provide a varying degree of mobility functionality and/or a different quality of service levels and/or different levels of security measures and/or a varying degree of identity handling.
Depending on the use case of the telecommunication device, different network service capabilities can be exposed to particular (mobile) devices which in turn, depending on their use case, can book such services (or service capabilities) and be provisioned with the related service capabilities.
The main advantage of the method and/or the mobile communication network and/or system according to the present invention compared to current methods and/or systems is that - depending on the use case and depending on the specific set of service capabilities used by a specific telecommunication device - procedures can be skipped due to the fact that they are unnecessary for this given use case. It is thereby advantageously possible, that the system definition and implementation can be significantly simplified.
A simple scenario according to the present invention is the applicability of different mobility-related capabilities of the mobile communication network of telecommunication devices with no data loss. E.g. while it is clear that a mobile device like a smartphone requires full mobility support (as the user might use the device while travelling with full speed), a stationary metering sensor typically has no mobility requirements at all - thus, regarding the group of mobility-related service capabilities of the mobile communication network, different service capabilities should be applied to different telecommunication devices when providing communication services to such devices.
In all conventionally known cellular systems (e.g. of the third generation mobile communication networks and/or of the fourth generation mobile communication networks), the underlying assumption has always been that there is typically no differentiation in terms of support of generic features like mobility, link layer reliability by for example retransmission, authentication and security requirements.
In this regard, a set of given network features (or set of service capabilities of the conventionally known mobile communication networks) for the above mentioned application scenario have always been utilized by all different telecommunication devices for any of the requested service.
Capabilities of the mobile communication network have - in conventionally known mobile communication networks - never been exposed in this sense to the telecommunication devices as the underlying assumption has always been that the terminal (or telecommunication device) has to utilize the network features typically always.
According to the present invention however, the method comprises the step of establishing a connection or initiating an exchange of data between the mobile communication network and the plurality telecommunication devices such that - prior to or upon either the establishment of the connection or the initiation of the exchange of data - a service capability information is sent from the mobile communication network to at least part of the telecommunication devices of the plurality of telecommunication devices, wherein the service capability information indicates at least part of the available service capabilities - within the groups of service capabilities - to the telecommunication devices of the plurality of telecommunication devices.
Thereby, it is advantageously possible that there is an exchange of information between the mobile communication network and the telecommunication device such that a differentiation of the service capabilities of the mobile communication network towards this telecommunication device (with respect to the service capabilities of the mobile communication network towards other telecommunication devices within the mobile communication network) is possible.

Thereby, it is advantageously possible that the transmission of the service capability information is by means of a dedicated signalization, i.e. the transmission is provided specifically for a specific telecommunication device. Alternatively or cumulatively, it is also possible according to the present invention that the transmission of the service capability information is provided by means of a broadcast such as on a broadcast control channel (BCCH); the broadcast control channel being typically received by a plurality of telecommunication devices (this plurality of telecommunication devices comprising the respective telecommunication device).
According to the present invention it is furthermore preferred that a service capability selection information is sent to the access network by at least a first telecommunication device of the plurality of telecommunication devices, the service capability selection information at least implicitly indicating one or a plurality of service capabilities in at least one group of service capabilities.
It is thereby advantageously possible that the telecommunication device transmits a choice regarding the offered service capabilities of the mobile communication network by means of transmitting the service capability selection information.
It is possible and preferred according to the present invention that by means of transmitting the service capability selection information, a set of choices (regarding different groups of service capabilities) of the telecommunication device is transmitted to the mobile communication network.

In Figure 1, a mobile communication network 100, especially a public land mobile network 100, is schematically shown, the mobile communication network 100 comprising an access network 110 and a core network 120. The mobile communication network 100 is preferably a cellular telecommunications network comprising typically a plurality of network cells (or radio cells), wherein two neighboring network cells (or radio cells) are represented in Figure 1 by means of reference signs 10 and 11. The mobile communication network 100 typically comprises a plurality of user equipments or telecommunication devices.

The access network 110 of the mobile communication network 100 comprises, in the exemplary representation of Figure 1, a first base station entity 111, serving the (first) radio cell 10. Furthermore, a neighbor (second) base station entity 112, serving the neighbor (second) radio cell 11, is schematically shown. The base transceiver stations 111, 112 are typically base stations or base station entities, e.g. a NodeB or an eNodeB base transceiver station.
In order for the mobile communication network 100 to provide communication services to the telecommunication devices 21, 22, 23, it is necessary that a connection is established between the mobile communication network 100 and one or a plurality of the telecommunication devices 21, 22, 23 and/or that an exchange of data is initiated between the mobile communication network 100 and one or a plurality of the telecommunication devices 21, 22, 23.
According to the present invention, prior to the establishment of a connection between one of the telecommunication devices 21, 22, 23 with the mobile communication network 100, or upon the establishment of a connection between one (or a plurality) of the telecommunication devices 21, 22, 23 with the mobile communication network 100, a service capability information (hereinafter designated by means of reference sign 201, cf.

The mobile communication network 100 is able to offer a plurality of available service capabilities, either to all of the telecommunication devices 21, 22, 23 or to a subset of the telecommunication devices 21, 22, 23.

Preferably, the service capability information 201 is transmitted by means of a dedicated signalization or on a broadcast control channel (BCCH) such that the broadcast control channel is received by at least part of the telecommunication devices 21, 22, 23. The service capability information 201 is preferably transmitted using SIBs (System Information Blocks) of the broadcast control channel (typically by means of specific broadcast messages that are capable of providing this information on the broadcast control channel). Alternatively or cumulatively, the service capability information 201 can be transmitted by means of dedicated signalization (e.g. context activation of specific telecommunication devices 21, 22, 23).
It is furthermore preferred that a service capability selection information (hereinafter designated by means of reference sign 202, cf. Figure 2) is sent to the access network 110 by at least one of the telecommunication devices 21, 22, 23 (e.g. the first telecommunication device 21 or the second telecommunication device 22). The service capability selection information 202 at least implicitly indicates one or a plurality of service capabilities in at least one group of service capabilities that the (first or second) telecommunication device 21, 22 choses (or books).

At a given first point in time, the service capability information 201 is transmitted from the mobile communication network 100 (i.e. a network node of the mobile communication network, typically a network node of the access network 110) to the telecommunication devices 21, 22, 23 (or at least part thereof, i.e. the first and/or the second and/or the third telecommunication device 21, 22, 23). At a given second point in time, the service capability selection information 202 is transmitted from at least one of the telecommunication devices 21, 22, 23 to the mobile communication network 100, typically a network node of the access network 110. The first given point in time can be equal for all the telecommunication devices 21, 22, 23 within a radio cell 10, 11 and the service capability information 201 transmitted by means of a broadcast transmission within the radio cell 10, 11. The second given point in time can vary for each telecommunication device 21, 22, 23 individually, i.e. the transmission of the service capability selection information 202 might occur at different points in time for different telecommunication devices 21, 22, 23.
The bookable services or service capabilities (within certain groups of service capabilities) typically vary according the use case and/or the access mode (such as mobile access, WLAN hot spot access or machine to machine use cases.

Additionally or cumulatively, it is possible and preferred that a selection of suitable service capabilities is performed by the telecommunication devices 21, 22, 23.
A first example of possible use cases relates to smart metering by means of machine to machine communication, i.e. using machine type communication enabled telecommunication devices 21, 22, 23. For this use case, the group of service capabilities providing a varying degree of identity handling should be offered by the mobile communication network 100 and/or selected by the telecommunication devices 21, 22, 23.
